Specification of Letters Patent.

' Patented. July 28, 1908.

Application filed May 18, 1907. Serial No. 374,417.

To all whom it may concern."

Be it known that I, J OHN WILLIAM KEN- NEDY, a citizen of the United States, and a resident of Missoula, in the county of Missoula and State of Montana, have invented new and useful Im rovements in Flush- Valves," of which the ollowing is a full, clear, and exact description.

My invention relates to flush valves for water closets, and has for itsprincipal object to provide a reservoir connected with the bowl of the water closet, valves admittin water from the inlet pipe to the reservoir and to the-bowl of the water closet, the water supply being shut off when the water in the said owl reaches a predetermined level. By the 7 use of my invention, it is therefore impossible for the water to overflow the bowl.

Other objects of my invention are to provide a flush valve which is comparatively inexpensive to construct, one that is certain in its 0 eration and one which will in its operation eep the several parts clear and free from foul water and excretion.

Still other objects of greater or minor importance will appear hereinafter in the folowing description.

The construction shown in the drawings, forming part of this application, shows the approved form of my flushing valve, but I do not wish to limit myself thereto, as I consider myself entitled to all forms and embodiments of the invention, which may be held to fall within the scope of the appended claims.

Similar characters of reference refer to similar parts in all the figures, in which Figure 1 is a sectional view showing the reservoir and bowl of the closet, the valves being open; Fig. 2 is a similar'view showing the valves closed; Fig. 3 is a sectional elevation taken from the left side of Fig. 1; Fig. 4 is a plan view showing in section the connec tions above the reservoir; and Fig. 5 is a perspective view showing my flushing device applied to the bowl of a water closet.

By referring to the drawings, it will be seen that the bowl of the water closet has two orifices for pipes, 2 and 3 respectively, one above the other, with their centers about five and one-half inches apart. It will be seen that the orifice 3 has a short elbow 4 ointing downwardly to prevent any body om fallin into this connection.

My flushing valve has a reservoir 5, which may be oval or of any other approved shape,

with a pipe 6 at the bottom of its wall, the said pipe 6 being ada ted to be connected to the lower orifice 3 in t e basin. This connection may be made by the use of short pipes with suitable couplings, as shown in the drawings. Above the reservoir, there is a pipe 7 with an extensionS on the side nearest the bowl, this extension 8 having a pipe 9, which is adapted to be connected with the orifice 2 in the same way that the pipe 6 is adapted to be connected to the orifice 3. The top of the reservoir 5 is screwed down with thumb-screws 22, so that it can be removed at any time to examine the interior of the reservoir. A cook 23 may also be adjusted on the reservoir, to remove air or other gas when desired.

Communication between the reservoir 5 and the pipe 7, is permitted through an annular opening 10, which forms a valve seat, which is commanded 'by a fuller ball 11, which is adjusted on the rod 12, to any desired relative height by the nut 13, which fits on the threaded portion of the said rod. This rod 12 is rigidly secured to two cross pieces 14, which are secured in the central annular opening 15, in the float 16, which is inclosed in the reservoir and fits easily the walls thereof, but which does not extend to the top of the reservoir. This permits the float to move upwardly when water enters the reservoir, and the reservoir and float being both oval in shape, one is unable to rotate relatively to the other, and as the reser- .voir is firmly secured to the bowl by the pipe 6, the rod 12 of the float 16 may move up and down with the'float, but it always has the same surface turned toward the bowl. The upper end of the rod 12 is bent at ri ht angles toward the bowland this termina 17 is secured to a slide valve 18 b a swivel 19. This slide valve 18 is preferabfy made of copper, to which is aflixed a piece of rubber 20, of the same size and shape as the slide valve. The communication of the extension 8 with the pipe 9 forms a valve seat 21, which is commanded by the valve 18, the movement of the float 16 to the top of the reservoir 5 seating the valve 18 by means of the rod 12 connecting the two. By this upward vmovement of the float, the fuller ball'll closes the annular opening 10, and in order to insure that the valve seat 21 and the annular opening or valve seat 10 will be closed simultaneously, the fuller ball is adjusted to the i 1 A I proper height on the rod 12 by means of the nut 13 previously mentioned.

In the operation of the flushing valve, it will be observed. that when the outlet in the bowl is opened, the water level in the bowl is lowered, with the result that the float 16 falls to the bottom of the reservoir 5, and the valve seats 21 and 10 are opened, permitting the water from the inlet pipe to pass through the pipes 9 and 6 to the bowl until the opening in the bottom of the bowl is closed, when the water will enter the top of the pipe 7 from the inlet pipe or water supply, and that the outlet in the bowl being closed, the water will run into the bowl through the pipe 9 and also through the ipe 6 from the bottom of the reservoir, a though this latter communication is more or less impeded by the float 16. As the water rises in the bowl, the float in the reservoir in communication with the bowl through the pi e 6, is raised until the valve 18 and the in ler ball 11 on the rod'12, which is fastened to the float, close respectively the valve seats 21 and 10. The supply of water is thereby cut oii, and the water will remain at a level in the bowl, which will keep the float 16 in the reservoir 5 at such a height as to close the valve seats 21 and 10.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
